Northern Tilefish

Tilefish

Lopholatilus chamaeleonticeps

Size: to 42" and 50 lbs.

Habitat
Deep waters around offshore canyons

These strange deep-sea fishes are found in the walls of the offshore canyons, far below the range of scuba divers, although they are caught by deep-sea fishermen. Their population is extremely cyclical, with large die-offs from excessively warm water, and this precludes any long-term commercial fishery.

Building artificial reefs is a lot more than just throwing junk in the ocean. The material needs to meet standards for cleanness and suitability, and it needs to end up where it is intended, and not somewhere else. Concrete and stone are easy, as they go straight down wherever they are dropped.
